QmageDecoderWrapper

A wrapper for libQmageDecoder and partially libSkia, allows for QMG file decoding.

Setting up the Docker Container.

You need a docker container to run ARMv7 on x86 (or if you are using a native ARM machine you probably don't need a docker container)
The recommended distro for this would be Alpine

docker pull --platform linux/arm/v7 alpine:latest
docker run --privileged --cap-add=SYS_PTRACE --security-opt seccomp=unconfined --security-opt apparmor=unconfined -v .:/qmg -it alpine:latest
apk add make gcc g++ lld
cd qmg

You can also use Debian, but you'd need to patch the libQmageDecoder.so

docker pull --platform linux/arm/v7 debian:latest
docker run --privileged --cap-add=SYS_PTRACE --security-opt seccomp=unconfined --security-opt apparmor=unconfined -v .:/qmg -it debian:latest
apt update && apt install make gcc g++ patchelf lld
cd qmg
patchelf --replace-needed libc.so libc.so.6 ./lib/libQmageDecoder.so
patchelf --replace-needed libstdc++.so libstdc++.so.6 ./lib/libQmageDecoder.so

Building and running

To build

make build

To run

cd bin
LD_LIBRARY_PATH="../lib/:" ./qmdecoder {args} {filename}
# note: args are NOT required to run it, only the filename.
# you can access the help page by running
LD_LIBRARY_PATH="../lib/:" ./qmdecoder -h
